WINDOW. i 1- To all whom it may concern:

Be it known that I, GEORGE A. FAIR, a citizen of the United States, Aand residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved VVindow, of which the following is a specification.

The present invention has reference to a window and among. its'important features are a'windowframe andY a pair of mutually -counterbalancing vertically sldable sashes so arranged that when the sashes are open a short distance, without, however, uncover-y ing the window openingat the top or bottom, passages properly protected from rain and-wind, are formed at top and bottom for the admission and escape of air, together with means whereby the sashes are prevented from beingopenedv further from the outside, the object beingto secure ventila; tion at all times without danger of entrance by unauthorized'persons; a window frame and a lower sash vertically slidable therein,

said sash having a` ventilating lpassage through its lower rail which, when the sash is in lowermost position, lis entirely concealed and closed by the sill and ,wliich, when the sash is elevated, is opened'before the lower edge of the lower rail clears the window sill,-in other' words, before the window opening is uncovered; means adapt'- ed to be pocketed in said lower rail and also adapted to be extendedfrom the inner side thereof whereby'the entering current of: air is directed upwardly; upper Vand lower sashes arrangedY yto slide vertically, land 'a easement sash carried on the outside of said ment sash supported'on the outsideof theV first mentioned easement sash in suchmanner as to be capable of swingingabout a ver tical axis in'respect to thelatter whereby `a deadair space is formed and whereby access may be readily had tothepanes for'clean# ing purposes; a pair of verticallyislidable sash frames the upper ofA which .isof considerably` less yheight than the lower, each of the sash frames carrying a easement sash, whereby, when thev easement for the lower sash frame is opened,.the casementfor the upper sash frame maybe swung inwardly d Specification of Letters Patent.

throughk the opening to afford` ready access to the outer surfaces of the 'panes-for'washf ing ,a pair of vertically slidable sashfframes the upper of which is of considerablyless height than the lower.' each of the sash frames Acarryingboth ifnner and outer caselment sashes whereby dead air spaces are formed and whereby ready access to the outer surfaces of the panes may be had lin the manner stated. The. inventionfurther consists in the detailsfof'construction shown, described and claimed.

' .In the drawings, F'gure I is an elevation taken from the outside'of the-building,the

. (Fig. 3.) isformed of anfouter'por-tionl and an inner portion 2,n each preferably of chan# zontal sectiointhe sashes ybeing lowered in nel cross-section, the inner portion being` considerably higher than the outer-mani,- festly beth portions may be made of one piece; the lintel comprises the structure (the details of which may be `varied widely) designated as a whole by 3, together vwith the detachablesealing strip a; while the'.

Vstiles` are,` for the most rpart,formed 'of the *mainv channel-"shaped Vframe niembersjrr the jamb casings lt will .fbe'observed y that. the members 5 have welded` or other- `wisesecured to theirouter faces sash guiding flanges 8; thatthere is likewise provided vat their inner edges rigidly secured Y' sash guiding flanges 9,which maybe part of, angle irons lLO; and that resilient parting `strips 11 of substantially channel cross section and of considerable width, measured on aline perpendicular to theV plane of the window, are interposedmidway between theV i flanges 8 and '95 VOne edge" portion ll2 of yeach of the parting,v strips is preferablyfree.

. Thechannelsthusformed Lin the frame constitute guides for vertically slidable sashes, the construction ofV which. willbe more readily' understood when itis remembered that eachof'the sashes car-ries a caseeen (in fat FWO easements-lathe @mb-QdilSL05 ment shown) which is capable 'of swinging in respect thereto about a vertical axis.V It will also be helpful to remember that the easement for the lower sash is of greater dimension both horizontally and vertically than that of the upper sash. y

The stiles of the upper sliding sash are formed of outwardly opening channel members 13 having sealing strips 14 welded along the inner edge of their front faces. The upper rail 18 may be channel-shaped, or of box-shapeas shown, whereas the lower rail includes a substantially 1 section which may be formed by angle irons, the upturned flange 19 of which constitutes a sealing strip for the easement while the downturn'ed flange 20 forms part of the means for sealing the joint between the meeting rails of the sashes.

Pivoted to the inner edge of one of the stiles 13h14 at 21 is an inner easement having its stile nearest the pivots formed of channel members 22 and 23 arranged back to back, its other stile including the out-turned channel member 24, to the rear face of vwhich is secured the inwardly projecting plate 25. In like manner, the upper and lower rails are respectively formed of out-turned channel members 26-28 and plates 29-30 that form seats for the pane 31 against the front face of which vare retaining strips 32 of suitable construction. The stile 22-23 has vsupported upon its outer face pivots 34 upon which is mounted an outer easement comprising an upper rail 35, a lower lrail 36 and a stile 38, all of which may be of substantially 1 shape in cross section, whereas its stile adjacent the pivots is preferably formed of an angle bar 39, one leg of which', when Vin closed position, overlaps vthe edge of the member 23; The pane 40 and retaining strips 41 complete the easement.

For the purpose of locking the outer casement in the inner easement and the latter in the sliding sash frame both at top and bottom, the sash frame is provided with sockets 42 in which the ends of locking bars 43,*that are carried by the inner easement and pass through perforated guides 44 thereon, are adapted to be projected.. These bars are also adapted to pass through 'perforations 45 in stirrups or other members 46 rigid with the upper and lower rails of the outer easement, it being understood that the members 46 are in turn adapted to swing int-o lthe inner easement through appropriate slots in the outer wall of the lower rail. The locking bars 43 are connected to a rotatable crank 48 whichk is operated by a hand lever 49. 1

The lower sliding sash frame is preferably formed of a box-likey upper rail 50 having a flange 51. spaced therefrom to 'coe operate with the an'ge 20 for Vsealing purposes together with a downwardly projecting sealing flange 53. It is also preferably provided with a cap plate 54 which may lie just above a roller shade 55 and protect the latter from dust. Stiles 58-59, which cor-Y 63, is arranged to swing on pivots '64 carried by the rail from apposition wherein itis inclosed by the rail (as indicated in dotted lines, Fig. 3) to a position in'wlhich itprojects therefrom and directs the entering air current upwardly, as shown by the arrows, Fig. 3. Spring clips and 66 with which a projection 68 on the deector engages, retain the latter in the positions stated, and appropriate hand grips 69 on the interior of the deflector afford a ready means for withdrawing the latter.

Adjacent the upper limit of travel of the upper sash the frame V43-5--8 crarries'on its outer face a hood of suitableconstruction, preferably' appl-ate 71 of part cylindrical shape lhaving ends72, the lower face of the hood being provided with a screen 73, Thus y when the upper sash is lowered, air may escape from the room through the passage and screen.

The elements 79,--81- 82-1-83-84- -86-88-89-90 of the inner easement correspond, except in mattei' of size as hereinafter stated, respectively, totheelements 21-22-23 24-J` 25 26 -m 28293031 and 32 of the inner easement of the upper sash, and the elements 91-92-93-94 `95-9697 likewise correspond, respectively, to the elements 34-35-36-38-39- 40 and 41 of the outer easement of the upper sash. In similar manner the locking mechanism l(l0-lOl-1021031041`05106 iS substantially the same as the mechanism 42-4344454648-49 heretofore described. n

Connecting the sashes and passing vover suitably supported pulleys 108 vare chains 109 whereby they are caused to tend to mutually counterbalance each other, it being understood that thel upper rail of the upper sash is preferably supplied with heavy material suicient to render the weights of the sashes substantially equal. One element of each side of the window frame, for example, the member 10, is notched or socketed at a plurality of levels to receive the end of a latch plunger l12jwhich is pivoted to `an operating bar 113 "and 'Slfl'S' through a persons when the easements are closed, the slid- 1 ing sash frames 13-14 or 58-59, as the case may be, areprovided with brackets 1:22 (Fig. 1, not shown in other figures) which overlie the hinges 34 and 91 and prevent the component elements thereof from being disengaged from one another. While shown above but one of the hinges of each casef ment, the brackets may, of course, be employed above the remaining hinges.

Operation: I/Vhen the sashes are fully closed both entrances to the Ventilating passage through the lower rail are closed by the sill, thus insuring the formation of a dead air space in the lower rail and preventing such gusts of air as might pass in through seams were the passage closed at but one end. The deflector'being concealed, the appearance of the lower rail is substantially the saine as that of ordinary constructions. Now assuming that the lower sash is raised a distance suficient to enable the deiiector to be withdrawn but insuiicient to cause the Y lower rail to clear the sill, air passes in at the bottom and out at the top and rain is eifectually eXeluded-likewise unauthorized entrance is prevented by the engagement of the plungers 112 with the walls of the appropriate socket in the frame. The window is therefore as safe in Ventilating position as ordinary windows when l enabling a room or building to be, in effect, closed without interfering in any way with the circulation of air-a feature that does away with the reason by which timid persons are impelled to entirely close the windows when alone at night, and also makes it practical to maintain ventilation even when the house is left closed for long periods.

When it is desired to clean the panes of the lower sash, the levers 106 are turned entirely closed, thus enough to withdraw the bars 101 from the sockets`100, whereupon both inner and outer easements are swung inwardly on pivots 7 9 which affords access to the outer surface o the vouter easement, after which a furtherl movement of the lever 106 releases the Outer easement from the inner and enables the former to be' swung outwardly on pivots 91 vto allow access to the other surfaces of the glass panes. vThe easements of the lower sash being swung inwardlyand the upper sash being in registration with thelower, the panes of the upper sash easements (because of the less dimensions`v thereof)v may be swung inwardly through the openingin the lower sash and cleaned ina manner similar to that just described. y

Many featuresy ofthe invention are applicable to doors as well as windows, and regardless of the particular material or construction of the individual parts; I donot, therefore, wish to be limited except as indicated by the subjoi-ned claims.
